My bad I don’t know the answer to this question
Minimum probability is 0.05, so we have to choose n such that expected frequency corresponding to 0.05 probability should be at least 5.
Let n = 5
Expected frequency = n*p = 5 * 0.05 = 0.25 < 5
Let n = 25
Expected frequency = n*p = 25 * 0.05 = 1.25 < 5
Let n = 50
then
Expected frequency = n*p = 50* 0.05 = 2.25 < 5
Let n = 100
then
Expected frequency = n*p = 100* 0.05 = 5 = 5
Thus, for n = 100, we get expected frequency = 5,
Thus, the minimum number of times the spinner should be spun to conduct this test is 100.
